<p>Provided are a copper strip, a plated copper strip, and a lead frame which can form a surface coating layer with high reflectivity. The copper strip is mounted with a bottom coating layer growth surface on which a bottom coating layer grows. At least any one among regions consisting of an amorphous region or minute grain is formed on the bottom coating layer growth surface in order to uniformize the rate of the bottom coating layer on the bottom coating layer growth surface of the copper strip.</p> |
